WebDefinition Spurious emissions are unwanted emissions, emanating from the equipment under test. The frequency bands (in-band and out-of-band) and their corresponding spurious emission limits are specified by regulatory agencies such as the Federal Communications … WebSpurious emissions measurements. Spurious emissions are undesired radio frequency emissions outside the transmission’s frequency band. These emissions can interfere with other radio services and compromise the intended transmission’s quality. Many factors can contribute to spurious emissions in a power amplifier.
